Dog Ear Mites: Symptoms, Causes, Treatments, and Prevention
Ear mites are common parasites in dogs that inhabit the ear canal and feed on earwax and skin oils, causing significant discomfort and irritation.
Without regular cleaning, these ear mites’ presence can lead to severe itching, inflammation, and secondary infections.
Ear mites are transmissible and can affect dogs of all ages and breeds.
This guide will help you understand the symptoms, causes, treatments, and prevention of ear mites to ensure your dogs remain healthy.
What Are Ear Mites?
Ear mites are tiny, spider-like parasites that inhabit a dog's ear canal. They belong to the arachnid family and are related to ticks and spiders.
Female mites lay eggs inside the ear canal, which hatch within four days. The larvae will then feed on earwax and oils for about a week.
Adult mites generally live up to two months. Upon reaching adulthood, they will continue to reproduce and continue to feed on earwax, oils, and skin debris.
This is when symptoms like irritation and discomfort usually start.
Worse, these parasites are highly transmissible and can easily spread to other pets through direct contact.
Because mites are microscopic, they are difficult to spot with the naked eye.
This is why knowing the symptoms of ear mites is important for early detection and treatment.
Symptoms of Ear Mites in Dogs
Ear mites are highly contagious, not only to dogs but also to cats and other pets. Early detection and treatment are essential to prevent secondary complications like total deafness.
Here are 10 common signs of ear mites in dogs.
- Excessive Scratching: Persistent ear scratching is a primary sign of ear mites. Dogs may use their paws or rub their heads against furniture to alleviate the itching.
- Head-Shaking: Frequent and vigorous head shaking is a common response to the discomfort caused by ear mites. This behaviour helps dislodge the mites but also indicates irritation.
- Dark Discharge: Dogs with ear mites often have a dark, crumbly discharge resembling coffee grounds in their ears. This discharge consists of earwax, blood, and mite debris.
- Foul Odor: An unpleasant smell from your dog's ears often signals an ear infection or a serious infestation.
- Red or Inflamed Ear Canals: Your dog’s inner ear canals may appear red, swollen, and irritated due to the mites' activity and the dog's scratching.
- Irritability: Dogs suffering from ear mites may become more irritable and restless due to constant discomfort.
- Rubbing Ears: Dogs with ear mites often rub their ears against furniture or the ground to relieve itching and discomfort.
- Restlessness: Difficulty settling down and frequent changes in position can be observed in a dog who is trying to relieve the itching.
- Hair Loss Around Ears: Excessive scratching and rubbing can lead to hair loss around the ears.
- Skin Infections: Continuous scratching can cause breaks in the skin, leading to bacterial or fungal infections.
Causes of Ear Mites in Dogs
Ear mites spread through the following causes.
- Direct contact with infected animals
- Poor hygiene
- Susceptibility of the host animal
Understanding these causes is key to prevention and effective treatment.
Transmission
Ear mites typically spread between hosts due to close contact with other infested animals.
Your dog can pick them up from other animals, like dogs or cats.
This often happens in multi-pet households, kennels, grooming salons, and social interactions at parks.
Additionally, ear mites can survive in the environment for a short time.
This means that bedding, toys, and grooming tools can also become sources of infestation.
Poor Hygiene
Ear mites thrive in environments with poor hygiene, which is why it is important to regularly clean your dog's ears.
Skipping this important hygiene step will create an ideal environment for these parasites.
Additionally, a dirty living space can also become a breeding ground for ear mites.
Ensure your dog’s bedding, toys, and overall living spaces are clean to reduce the risk of ear mite infestations.
Certain Susceptibilities
Certain dogs are more susceptible to ear mites due to their age, health, and breed.
Puppies and older dogs, along with those with weakened immune systems, are at higher risk for infestations.
In addition, dog breeds with long, floppy ears, like Cocker Spaniels or Basset Hounds, are more likely to get ear mites.
This is because reduced air circulation in their ear canals creates an environment where mites can thrive.
Regular checks and ear hygiene are especially important for these susceptible groups to prevent infestations.
Diagnosing Ear Mites
It is important to know the difference between ear mites and other ear problems, like too much earwax or a yeast infection.
Though all three of the previously mentioned conditions may result in dark discharge, vets may need to examine them under a microscope to find any mites.
Here are things to expect during a vet visit.
- Visual Inspection
The vet will initially examine the dog's ears for signs of mites, such as dark discharge and inflammation.
To confirm the presence of ear mites, a sample of ear discharge is examined under a microscope. This helps in identifying the mites and their eggs.
- Otoscope Examination
In some cases, your vet might use an otoscope, a specialised instrument, to examine the ear canal more closely and confirm the diagnosis.
WARNING: Do not try to self-diagnose your dog's ear problems. Early detection and treatment are key to preventing complications.
Treatment for Ear Mites
Your vet will need to clean your dog’s ears and use the right medicine to get rid of ear mites.
Regular cleaning helps keep the area clean, but once your dogs have got ear mites, you will need specific treatment.
Here are common ways to treat ear mites in dogs.
Ear Drops
Vets often prescribe medicated ear drops designed to kill mites.
These drops must be applied directly into the ear canal, typically over several days or weeks, depending on the severity of the infestation.
Following the vet's instructions carefully is important to ensure all mites are eradicated.
Regular application is key to effective treatment.
Cleaning Solutions
Regular cleaning with specialised solutions helps remove debris and mites from the ear canal.
This not only removes existing mites but also creates an environment less hospitable to new infestations.
Cleaning should be done gently to avoid further irritation.
Prescription Medications
In severe cases, veterinarians may prescribe oral medications to help eliminate mites.
These medications work systemically, meaning they circulate through the dog's body to kill mites wherever they are found.
They are often used together with topical treatments for a more comprehensive approach.
Follow-up visits to the vet may be necessary to ensure the infestation is fully resolved.
IMPORTANT: Never use cotton swabs to clean your dog's ears. They can push debris and mites deeper into the ear canal, causing more damage.
Preventing Ear Mites
Preventing ear mites involves regular ear care and maintaining a clean space for your dog.
These measures help reduce the risk of infestations and promote overall ear health.
- Regular Ear Cleaning
Clean your dog's ears regularly using a veterinarian-recommended cleaning solution. This helps remove earwax, dirt, and debris that can harbour mites.
- Avoiding Infested Animals
Limit your dog's playtime with animals known or suspected to have ear mites.
This is especially important in high-risk environments like kennels and dog parks, where close contact with other dogs can facilitate the transmission of ear mites.
- Routine Veterinary Check-Ups
Schedule regular check-ups with your veterinarian.
These check-ups allow your vet to examine your dog's ears for any signs of trouble, including an ear mite infestation.
Early detection and treatment of ear mite infestations can prevent severe complications.
- Good Hygiene Practices
Maintaining a clean living environment and regular grooming go a long way towards preventing ear mites.
Regularly wash your dog's bedding, toys, and grooming tools in hot water to eliminate any possible mites or eggs.
This will prevent them from establishing themselves in your home or within your dog’s ears.
